6 FAQs about Large-scale Solar Power Generation & Energy Storage
What is phosphosilicate glass (PSG) layer?
Commonly, the dopant source grown on the silicon surface during the deposition step of POCl3 diffusions is referred to as the phosphosilicate glass (PSG) layer. Actually, the PSG layer is separated from the silicon surface by a thin silicon dioxide (SiO2) layer featuring a much lower phosphorus concentration .
How do phosphorus silicate glass layers affect PV efficiencies?
Phosphorous silicate glass (PSG) layers were carefully designed on an emitter layer to determine how they affect the efficiencies of solar cells before and after PID. A current-voltage (I-V) tester was used to determine PV parameters. An ellipseometer and transmission electron microscope (TEM) were used to measure the thicknesses of the PSG layers.
Does phosphorus doping affect crystalline silicon solar cells?
Effective control of the dose of diffused phosphorus emitter profiles is crucial for optimization of crystalline silicon solar cells, but it requires detailed understanding of the POCl3 doping process.
Where is phosphosilicate glass used?
Present address: Global Photovoltaic Simulation Group, Case Postale 1056, 1211 Geneva 1, Switzerland. The phosphosilicate glass (PSG), fabricated by tube furnace diffusion using a POCl 3 source, is widely used as a dopant source in the manufacturing of crystalline silicon solar cells.
